Features:
- Serves DCS800 D1 through D4+ converter modules across the documented 20–1190 A range.
- Automatically adapts its auxiliary input to 115 or 230 V AC for the internal low-voltage supply.
- Combines armature firing and measurement with onboard field-exciter control and field-current measurement.
ABB SDCS-PIN-4B 3ADT316300R1510 sits between the DCS800 control board, thyristor power stage, measurement circuits, and internal power supply.
The X99 auxiliary input feeds the low-voltage rails, while separate connectors carry armature firing, voltage and current measurement, relay output, and field-circuit functions.
Converter size determines which armature and field interfaces are used, so installation checks must follow the D1–D4+ hardware arrangement rather than the board outline alone.
The ABB SDCS-PIN-4B 3ADT316300R1510 Drive Interface and Power Supply Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Auxiliary-to-Low-Voltage Path
- Input point: Auxiliary power enters the board through X99.
- Automatic selection: The 4B version adapts automatically to 115 or 230 V AC.
- Internal rails: The board creates the small drive voltages used by the converter and connected options.
- Input protection: Hardware filtering, voltage limitation, and recommended fusing define the supply boundary.
Firing and Measurement Functions
- Firing channels: The interface fires an armature bridge with six or twelve thyristors.
- Voltage sensing: High-resistance circuits measure both AC and DC voltage.
- Current sensing: Current-transformer interfaces provide armature current measurement.
- Thermal input: A PTC interface carries heatsink-temperature information.
Onboard Bridge Control
- Converter range: The onboard field interface applies to D1 through D4 converters.
- Pulse path: Mains-synchronized pulses are amplified before reaching the field bridge.
- Bridge form: The onboard field stage is a three-phase half-controlled bridge.
- Current scaling: Field-current measurement is scaled from the rated motor field current.
Circuit-Specific Boundaries
- Snubber path: The board works with the heatsink resistor to protect the thyristor circuit.
- Field fuses: F100, F101, and F102 are used for available motor field-winding protection.
- Relay contact: X96 provides an isolated normally open relay output.
- Size-dependent cabling: Wire size and fuse selections change across D1, D2, D3, and D4 converter ratings.
